Abu al-Walid was a Saudi Arabian of the Ghamd tribe who fought as a "mujahid" volunteer in Central Asia, the Balkans, and the North Caucasus. He was killed in April 2004 in Chechnya by the Russian federal forces.

Mujahideen, or Mujahidin, is the plural form of mujahid, an Arabic term that broadly refers to people who engage in jihad, interpreted in a jurisprudence of Islam as the fight on behalf of God, religion or the community (ummah).
